Skeleton reaver bugs, ruin, skeleton skill

[Pahasusi]

Hello,

some bugs I have found with 1.2.1 and 1.2.2, concerning at least reaver:

* Ruin doesn't heal anymore (skeleton reaver, ruin activated but doesn't heal when bumping monsters)
* Stats have some kind of adding/rounding error: Skeleton skill adds str/dex, but the added stats are not calculated correctly to stat total concerning weapon / skill increase. If you have exact stat requirement met with skeleton skill, you need to have +1 stat to actually be able to take the skill / use weapon.
